Satellite Cells Cns Or Pns
Schwann cells neurolemma of the pns mirror the role of oligodendrocytes in the central nervous system.
Satellite cells cns or pns. Many types of glia may be found in the cns e g astrocytes microglia oligodendrocytes and pns schwann cells satellite glial cells each of which serves a distinct set of functions. Satellite glial cells or satellite cells formerly called amphicytes are glial cells that cover the surface of neuron cell bodies in ganglia of the peripheral nervous system thus they are found in sensory sympathetic and parasympathetic ganglia. Glia also called glial cells or neuroglia are non neuronal cells in the central nervous system brain and spinal cord and the peripheral nervous system that do not produce electrical impulses. Glia are critical elements in the normal cns and pns.
Carries sensory information from pns sensory receptors to cns. Enteric glial cells. Satellite cells schwann cells. Satellite cells are small flattened cells found in the ganglia of the peripheral nervous system ganglion collection of cell bodies.
Both satellite glial cells sgcs and schwann cells the cells that ensheathe some nerve fibers in the pns are derived from the neural crest of. They may contribute to chronic pain. Central nervous system and peripheral nervous system. The neurons that have satellite cells make up something called gangila which are.
Similar to oligodendrocytes in the central nervous system schwann cells myelinate neurons in the peripheral nervous system. Satellite cells play an important role in modulating the pns following injury and inflammation. Functionally the schwann cells are similar to oligodendrocytes of the central nervous system cns. Recent investigations indicate that the various.
They maintain homeostasis form myelin and provide support and protection for neurons. Largest and most numerous produce feet projections that surround blood vessels. In the central nervous system glial cells include oligodendrocytes astrocytes ependymal cells and microglia. Satellite cells main purpose appears to be regulation the environment around the neurons keeping chemicals in balance.
Each cns neuron is supported by 10 50 glial cells. Satellite cells surround neurons in the sensory sympathetic and parasympathetic ganglia and help regulate the chemical environment. Satellite cells are found in the peripheral nervous system however as opposed to astrocytes which are found in the central nervous system. Ependymal cns cell that form the linings.
Macroglia contained in the peripheral nervous system are satellite glial cells schwann cells and enteric glia.
